BACKGROUND OF THE DISCLOSURE

High blood pressure, also known as hypertension, is a leading cause of preventable morbidity and mortality and it is well established that treatments that lower blood pressure (BP) are beneficial. However, despite the plethora of blood pressure lowering medicines available, many patients continue to have poor blood pressure control as evidenced by multiple large-scale population studies. Contributing factors for poor blood pressure control include poor adherence, complex guidelines recommending multiple up-titration steps, and treatment inertia. Furthermore, the majority of treated patients receive only monotherapy, which has limited potency even at high doses where side effects are increased and tolerability reduced. Accordingly, there exists a need for new treatments for lowering high blood pressure that are efficacious and tolerable.

The main objectives were to assess whether there were differences in the effects of combinations utilizing different drugs from the same class, and differences between combinations utilizing the same drugs at different doses, including very low doses (i.e., doses below the lowest doses approved and manufactured, such as those at 50% of the lowest hypertension therapeutic dose (LHTD).

The specific combinations studied were:

-   -   Combination 1: telmisartan, amlodipine besylate, and indapamide,         all at 50% of the lowest hypertension therapeutic dose (LHTD) or         one-quarter of the FDA recommended usual maintenance dose         (corresponds to telmisartan 10 mg, amlodipine besylate 1.25 mg,         and indapamide 0.625 mg);     -   Combination 2: telmisartan, amlodipine, and indapamide, all at         100% of the lowest hypertension therapeutic dose (LHTD) or         one-half of the FDA recommended usual maintenance dose         (corresponds to telmisartan 20 mg, amlodipine besylate 2.5 mg,         and indapamide 1.25 mg); and     -   Combination 3: losartan, amlodipine besylate, and         hydrochlorothiazide, all at 100% of the lowest hypertension         therapeutic dose (LHTD) or one-half of the FDA recommended usual         maintenance dose (corresponds to losartan 25 mg, amlodipine         besylate 2.5 mg, and hydrochlorothiazide 12.5 mg).

The study was conducted in spontaneously hypertensive rats (SHR), the most commonly-used animal model for the study of hypertension (See: Pinto Y M, Paul M, Ganten D. “Lessons from rat models of hypertension: from Goldblatt to genetic engineering”. Cardiovascular Research. 39 (1): 77-88.). Drug doses were calculated using standard allometric scaling methods and data from the published literature on C_(max) and AUC for each of the six antihypertensive agents. Each animal was exposed to a single dose of every drug combination in a Latin square design.

Methods

The following was used as the vehicle for the following study: 0.5% methylcellulose (w/v) and 0.25% polysorbate 80 (v/v) in 25 mM phosphate buffer at pH 8+/−0.2.

The following animals were used in the study: Spontaneous Hypertensive rats (Strain: SHR/NCrl). The rats were obtained from Charles River Laboratories, Inc., Kingston, N.Y. The age at initiation of dosing was at approximately 12 weeks. 13 male rats were used for acclimation. 8 male rats were used for the study. The animals were identified by cage card and tattoo.

Telemetry Implantation: The animals were implanted with Data Science International transmitters (HD-S10) for collection for blood pressure and heart rate data. The animals were not administered dose formulations until at least 10 days after surgery.

Housing: The animals were individually housed in solid bottom cages equipped with water bottles.

Diet: Teklad Global Diet—Rodent 2014 (Envigo RMS, Inc.) were provided ad libitum unless otherwise specified. In some instances, the animals were fed the meal-form of this diet if indicated by health conditions.

Water: Greenfield city water was provided ad libitum.

Contaminants: No known contaminants were present in the diet, water, or bedding (if applicable) at levels that would interfere with this study.

Environment: Environmental controls for the animal room were set to maintain the following room conditions: a temperature range of 20 to 26° C., a relative humidity of 30 to 70%, and a 12-hour light/12-hour dark cycle.

Acclimation (Pre-dose Phase): The acclimation phase was for a maximum of 1 week.

Environmental and Dietary Enrichments: The animals were given various cage-enrichment devices and dietary enrichment (that do not require analyses).

Randomization: The animals were arbitrarily selected based on pre-dose phase mean arterial pressure values.

The following table shows the group designation of the rats used in the study:

The following table shows the dose levels administered in the study:

TABLE 4 Dose Dose Dose Level Concentration Volume Test Article (mg/kg/day) (mg/mL) (mL/kg) Combi- Telmisartan 0.17 0.017 10 nation 1 Amlodipine Besylate 0.22 0.022 Indapamide 0.08 0.008 Combi- Telmisartan 0.34 0.034 10 nation 2 Amlodipine Besylate 0.44 0.044 Indapamide 0.16 0.016 Combi- Amlodipine Besylate 0.44 0.044 10 nation 3 Losartan Potassium 0.31 0.031 Hydrochlorothiazide 1.74 0.174 Vehicle 0.5% Methylcellulose 0 0 10 (w/v), 0.25% polysorbate 80 (v/v), in phosphate buffer, pH 8 +/− 0.2

Dosing Procedures: For Combinations 1, 2 and 3, each test combination formulation was prepared fresh on each day of dosing. A portion of the vehicle (approximately 80%) was added to the test combination formulation and mixed until the preparations were homogenous. If a homogenous suspension or solution was not obtained, 1N NaOH and/or 1N HCl was added to adjust to pH 9+0.2. The remainder of the vehicle added and mixed with a stir bar. The test combination formulations were stirred continuously at room temperature and protected from light for approximately 30 minutes prior to and throughout dosing. The test combination formulations were stored protected from light, stirring in a refrigerator set to maintain 2 to 8° C.

Dosing Procedures: For pre-dose handling, the test combination formulations were allowed to equilibrate to approximately room temperature for at least 30 minutes prior to dosing. The animals were dosed at the volume of 10 mL/kg, and the actual dose volume was based on the most recent body weight. Oral gavage was used to administer the dose. The dose interval was once daily on Days 1, 8, 15, and 22. Following dose administration, the remaining test combination formulations were disposed of according to standard operating procedures.

Telemetry Collections: The animals were not disturbed or manipulated immediately prior to and during telemetry data collection without prior authorization. Such disturbances include but were not limited to cage changes, bedding changes, mopping, sanitation, or anything that would disturb the natural quiet environment that was important for collection of the cardiovascular telemetry data

Animal Observation: Each rat was observed once daily in the morning. Any abnormal findings were recorded. The rats were observed for mortality, abnormalities, and signs of pain or distress. Any abnormal findings that were observed during the unscheduled observation periods were also noted.

Body Weight: The body weights were obtained at least once during the pre-dose phase and prior to each scheduled dose. Additional body weights were recorded to monitor animal health if appropriate. The animals were instrumented with a transmitter: a representative transmitter and leads were used to tare the balance prior to the collection of body weights for dose calculation purposes.

Telemetry Data Collection: The arterial pressure raw signals were digitized at a sampling rate of 500 Hz. Derived parameters in the pre-dose and dosing phases were the same. For pre-dose data collection, all implanted telemetry devices were checked for consistency of signal and to verify the telemetry signal was acceptable for analysis. The signal check consisted of at least one telemetry recording taken from each rat considered for the study. Telemetry data was recorded continuously for approximately 24 hours. The telemetry data was reviewed to determine if the rat was qualified for the study. The data was maintained in the study records and was used to calculate the nominal 24-hour mean arterial pressure average to support the randomization animal selection. For dosing phase data collection, continuous telemetry data was collected during the dosing phase starting at least 90 minutes prior to dosing through approximately 48 hours post-dose.

Nominal Dosing Time: The telemetry collection time points were based on a single nominal dosing time for all animals. The nominal dosing time for each day of the dosing phase were the end of dosing for the first half of animals dosed on that day recorded on each computer for all animals on that compute.

Telemetry Data Evaluation: Telemetry parameters, including heart rate (beats/minute), systolic pressure (mmHg), diastolic pressure (mmHg), mean arterial pressure (mmHg), and arterial pulse pressure (mmHg), were analyzed and reported. Telemetry data generated by Ponemah during the dosing phases were analyzed in 1-minute samples. Data was processed in 15-minute averages and were provided for data review. The 15-minute mean data was further averaged by binning into the following Analysis Periods:

-   -   Period 1: 0.5 to 2 hours post-dose;     -   Period 2: 2 to 4 hours post-dose;     -   Period 3: 4-8 hours post-dose;     -   Period 4: 8-12 hours post-dose;     -   Period 5: 12-20 hours post-dose;     -   Period 6: 20-32 hours post-dose (second light cycle); and     -   Period 7: 32 to 44 hours post-dose (second dark cycle).

Analysis

Blood pressure was measured over a 44-hour period using an implanted telemetry device. The primary outcome was systolic blood pressure.

Statistical analyses were conducted using all available data points, with weighting to reflect the non-uniform timing of measurements. Estimates of treatment effects were calculated using estimated differences between treatments using a mixed model (SAS 9.4, SAS Institute, Cary, N.C.) with a direct product autoregressive correlation structure to account for repeated measurements within individuals over time.

-   -   Results

Eight animals began the study; however, the telemetry transmitter failed in one animal. As a result, complete data was available from seven animals.

The following table shows the differences in systolic BP (mmHg) between treatments:

TABLE 5 Comparison Overall difference Estimate P-value between treatments Level (95% CI) 0.0004 Systolic BP (95% CI) Control 177.4  — (174.4-180.3) Combination 1 172.1  — (169.3-174.9) Combination 2 169.0  — (166.1-171.9) Combination 3 175.4  — (172.5-178.3) Treatment Control vs −5.3 0.0048 comparisons Combination 1 (−8.7-1.8)  Control vs −8.4 <.0001 Combination 2 (−11.5-5.2)  Control vs −2.0 0.2663 Combination 3 (−5.6-1.7)  Combination 1 vs −3.1 0.0720 Combination 2 (−6.5-0.3)  Combination 1 vs  3.3 0.0342 Combination 3 (0.3-6.3) Combination 2 vs  6.4 0.0009 Combination 3 (3.0-9.8)

FIG. 1 shows the mean systolic blood pressure (mmHg) across time periods by treatment. FIG. 2 shows the mean diastolic blood pressure (mmHg) across time periods by treatment. FIG. 3 shows the mean heart rate across time periods by treatment.

In this non-limiting example, the results demonstrated that Combination 1 produced significantly larger reductions in systolic blood pressure than Combination 3, and Combination 2 produced significantly larger reductions in systolic blood pressure than either Combination 3 or 1. These differences persisted over the full 44-hour period of observation. The results demonstrated that both Combination 1 and Combination 2 produced significantly larger reductions in systolic blood pressure than Combination 3. These differences persisted over the full 44-hour period of observation. There were similar differences between the three combinations in the reduction in DPB, and no differences between the combinations in heart rate.

In this non-limiting example, these results demonstrate unexpected differences between the telmisartan, amlodipine besylate, indapamide combinations and the losartan, amlodipine besylate, hydrochlorothiazide combination. Specifically, at equivalent or lower doses, the telmisartan, amlodipine besylate, and indapamide combination produced significantly larger reductions in blood pressure than the combination of losartan, amlodipine besylate, and hydrochlorothiazide. As the amlodipine besylate dose was the same in Combination 2 and 3, the results demonstrate previously unknown differences in the effectiveness of specific angiotensin II receptor blockers and specific diuretics (such as a thiazide diuretic versus a thiazide-like diuretic) when provided in parallel with amlodipine besylate.

Example 2: Triple Combination Composition Therapy for the Treatment of Hypertension Methods

This study is a randomized, placebo-controlled, double-blind cross-over trial. The study is divided into three phases. During the first phase (4 weeks) participants are randomized (1:1) to either receive the triple combination composition therapy or Placebo. This is followed by a two week washout (placebo) and subsequently participants are crossed over to the opposite arm to receive the other treatment for four weeks. Participants are recruited from the community, predominantly through community general practices in western Sydney, Australia.

Participants

Participants are eligible if they met the following inclusion criteria: 1) adults aged 18 years and over, 2) office SBP >140 mmHg and/or DBP >90 mmHg on 2 readings on separate days; plus baseline ambulatory SBP >135 and/or DBP >85; 3) Not on medical treatment for hypertension. Exclusion criteria included: No definite contraindication to one or more component medications in the triple combination composition; the responsible clinician felt a change in current therapy would place the patient at risk; severe or accelerated hypertension; pregnancy; inability to provide informed consent; and medical illness with anticipated life expectancy less than 3 months.

Intervention

For these studies, either the triple combination with each component at 50% of the lowest hypertension therapeutic dose (LHTD) or the triple combination with each component at 100% of the lowest hypertension therapeutic dose (LHTD) will be tested.

If the study is testing the triple combination with each component at 50% of the lowest hypertension therapeutic dose (LHTD), then the test composition is as follows. The triple combination composition is a single encapsulated pill containing the three following components in the specified amounts: telmisartan 10 mg, amlodipine besylate 1.25 mg, and indapamide 0.625 mg. The placebo capsule appears identical and contains placebo tablets of similar weight to those in the triple combination composition.

If the study is testing the triple combination with each component at 100% of the lowest hypertension therapeutic dose (LHTD), then the test compositions is as follow. The triple combination composition is a single encapsulated pill containing the three following components in the specified amounts: telmisartan 20 mg, amlodipine besylate 2.5 mg, and indapamide 1.25 mg. The placebo capsule appears identical and contains placebo tablets of similar weight to those in the triple combination composition.

Participants are administered a single pill, triple combination composition or placebo, throughout the trial. Patients are instructed to take the tablets at the same time each day and are encouraged to take this in the morning, but the time of the day (morning or evening) is at the patient's preference.

All trial medicines are prepared by a TGA-cGMP (Therapeutic Goods Australia—certificate of Good Manufacturing Practice) licensed manufacturing facility. If appropriate, low strength doses are obtained by halving half-strength doses using a pill splitting device, without crushing, and are weighed to ensure accuracy of halving doses. The low strength doses are than encapsulated using gelatin capsules (DBCaps-Capsugel). The capsules are stored in a cool dry place and monitored using temperature loggers, until they are dispensed.

Treatment allocations are blinded to both study staff and participants. In addition to the study drugs, all participants are offered education on healthier lifestyle options as recommended by guidelines for hypertension management.

Randomization

A computer assisted randomization sequence is generated by a statistician and supplied to the pharmaceutical packaging company. The research assistant, recruitment team, investigators are blinded to this sequence. For each patient i.e. allocated randomization number, the pills are packaged into three child-resistant packs corresponding to three phases of the study. All packs have identical appearance ensuring blinding of patient and research staff. Subsequently the medication packs are prescribed in an organized sequence.

Outcomes and Data Collection

The primary outcome is reduction in mean 24 hour systolic blood pressure at 4 weeks using ambulatory blood pressure monitoring (ABP). The secondary outcomes include:

-   -   a. Reduction in mean 24 hour diastolic blood pressure, and in         daytime and nighttime SBP and DBP at 4 weeks     -   b. Reduction in office SBP and DBP as measured by a standardized         automated blood pressure cuff     -   c. Proportion with controlled blood pressure at 4 weeks, defined         as <135/85 mmHg 24 hour BP and <140/90 mmHg office BP     -   d. Adverse events and pre-specified adverse events by laboratory         parameters: Rise in transaminases (ALT/AST) more than 3× upper         limit of normal or doubling if baseline levels known to be         elevated; drop in estimated glomerular filtration rate by >20%         as estimated from serum creatinine; sodium, potassium and uric         acid levels     -   e. Assessment of acceptability and tolerability

Patients will undergo 24 hour ABP monitoring 4 times—baseline (off study drug), 4 weeks (on phase 1 drug), 6 weeks (on placebo), and 10 weeks (on phase 3 drug). In order to minimize inconvenience, patients are referred for ABP to a lab. The ABP units are calibrated at regular intervals by the lab according to the manufacturer's specification. To minimize variability, the follow up readings are repeated from the same collection center using the same brand device. Participants are reimbursed nominal amounts to cover travel and parking costs. Study medications and investigations are provided at no cost to participants. Office BP is recorded three times at each visit using an OMRON T9P (HEM-759-C1). The second and the third readings are averaged for study analysis. In addition at week 4 and 10 patients will undergo blood tests to assess for biochemical side effects, are administered a questionnaire for clinical side effects, and compliance is assessed by self-report and pill count. Patients will remain blinded to their treatment allocation when completing this questionnaire.

Drug acceptability and tolerability are also assessed at the end of the study. All adverse events are recorded. In addition, clinical adverse events possibly associated with blood pressure lowering medications: dizziness, blurred vision, syncope/collapse, chest pain/angina, shortness of breath, cough, wheeze, pedal oedema, skin rash, itching are specifically asked about.

The trial has a simplified data safety and management committee of two core members with expertise in clinical medicine, trials and statistics. A single meeting convenes when 10 patients are randomized to the trial to review safety, and the study is advised to continue.

Statistical Considerations

A sample size of 50 patients is planned to provide 90% power at p=0.05 to detect a SBP difference of 12 mmHg between the intervention and control assuming a SD of the within patient difference of 12 mmHg, taking into account the possibility of a 10% loss to follow-up.

Statistical Approach

Analyses are conducted on an intention to treat basis. All tests are two-sided and the nominal level of a is 5%. All statistical analyses are unadjusted for prognostic covariates. We will report compliance to the study drug using data on pills (doses) taken and missed doses over the time period.

A linear mixed model is used to estimate the effect of the treatment on change in blood pressure from baseline for each treatment period, according to the Kenward and Roger approach (Kenward M G, Roger J H. The use of baseline covariates in crossover studies. Biostatistics 2010; 11(1): 1-17.) In order to appropriately adjust for baseline levels, collected at the beginning of each treatment period (week 0, week 6), this method uses all measurements (baseline and follow-up, in both period) as outcomes, but accounts for covariance between measurements within individuals (Liu G F, Lu K, Mogg R, Mallick M, Mehrotra D V. Should baseline be a covariate or dependent variable in analyses of change from baseline in clinical trials? Stat Med 2009; 28(20): 2509-30). A linear contrast between the variables denoting period (first/second), type of measurement (baseline/final), and treatment received (placebo/triple combination composition) produces an unbiased estimate of effect of the triple combination composition on change in blood pressure compared to the placebo. All available data are included in the model, no missing data is imputed. If a patient is missing data for one period, data from the available period are used. A sensitivity analysis is carried including only patients with data available from both periods to see if the effect of treatment is modified. There is also adjustment of the denominator degrees of freedom of Kenward and Roger (2009) that is optimal for smaller sample sizes (Kenward M G, Roger J H. An improved approximation to the precision of fixed effects from restricted maximum likelihood. Computational Statistics & Data Analysis 2009; 53(7): 2583-95).

Testing for carry over will use an unpaired t-test of the main outcome with order as an effect. Period effect is tested by using a paired t-test comparing the main outcome in period 1 with main outcome in period 2 from the same patient. A sensitivity analysis is also performed using normal paired t-test to compare primary outcome between different period (different treatment) from the same patient, ignoring the baseline level of each period.

Continuous secondary endpoints with baseline values (e.g., daytime/night-time ambulatory SBP/DBP) are analyzed similarly to the primary endpoint. Other continuous variables without a baseline value in each period are analyzed with a paired t-test. Counts and percentages of all adverse events are reported. As a sensitivity analysis, the analyses are repeated on the complete cases (i.e. full data for each measurement period).

Tests for interaction of treatment effect with age (<=60 vs. >60 years), gender, and BMI (<=30 vs. <30 kg/m²). Subgroup analyses for each variable are also conducted. All analyses are conducted using SAS 9.4 (Cary, N.C., USA) on software.

Example 3: Comparative Study of Triple Combination versus Standard Dose Monotherapy for the Treatment of Hypertension Objectives

The primary objective of this study is to investigate in a double blind randomized controlled trial whether initiating treatment with a triple combination therapy will lower blood pressure more effectively, and with fewer side effects, compared to initiating standard dose monotherapy as per current guidelines in patients with hypertension. The secondary objective is to assess if this approach is safe and has fewer side effects compared to standard care. Study Design

This will be a 12-week double blind randomized controlled trial (1:1) of 650 patients with grade 1 and 2 essential hypertension. Subjects will be randomized through a central computer-based randomization service, to initial therapy with the triple combination composition or to an angiotensin receptor blocker (ARB), with option to add a calcium channel blocker (CCB) as required, as per current Australian Hypertension guidelines. The primary outcome will be reduction in mean systolic blood pressure using standardized automated BP cuff at 12 weeks. Secondary outcomes will include: proportion with controlled blood pressure at 6 weeks, 12 weeks, ambulatory blood pressure (ABP) measures and tolerability/occurrence of adverse events.

If the study is testing the triple combination with each component at 50% of the lowest hypertension therapeutic dose (LHTD), then the test composition is as follows. Patients who meet criteria for inclusion will be randomized to: 1) A combination pill comprising the following three components—telmisartan 10 mg, amlodipine besylate 1.25 mg, and indapamide 0.625 mg; or 2) telmisartan 40 mg.

If the study is testing the triple combination with each component at 100% of the lowest hypertension therapeutic dose (LHTD), then the test composition is as follows. Patients who meet criteria for inclusion will be randomized to: 1) A combination pill comprising the following three components—telmisartan 20 mg, amlodipine besylate 2.5 mg, and indapamide 1.25 mg; or 2) telmisartan 40 mg.

Patients who are currently on monotherapy will be asked to stop their treatment while they are taking the study treatment. At 6 weeks if the BP is greater than 140/90 mmHg in either arm amlodipine besylate (5 mg) will be added by study staff.

Outcomes

The primary outcome will be the difference between groups in mean automated office systolic blood pressure at 12 weeks adjusted for baseline values.

The secondary outcomes include the following:

The 24-hour ambulatory blood pressure measures

-   -   a. Difference between groups in mean 24-hour SBP and DBP at 12         weeks     -   b. Difference between groups in mean change in 24-hour SBP and         DBP from 0 to 12 weeks     -   c.

Difference between groups in daytime, night-time, and 24 hour         BP load (percentage area under the blood pressure curve above         normal day, night, and 24 hour values as per NHFA Guide to         management of hypertension 2008)     -   e. Difference between groups in the proportion of non-dippers         (night-time BP is not more than 10% lower than average daytime         BP as per NHFA Guide to management of hypertension 2008) and         coefficient of variability of BP (O'Brien, E., G. Parati, and G.         Stergiou, Hypertension, 2013. 62(6): p. 988-94).

Other blood pressure measures in the triple group vs control groups:

-   -   a. Change in mean diastolic blood pressure from baseline to 12         weeks,     -   b. Hypertension control (% with SBP <140 mmHg and DBP <90 mmHg)         at 6 and 12 weeks,     -   c. Percentage requiring step-up treatment at 6 weeks     -   d. Percentage with both BP control (as defined above) and no         adverse events.     -   e. Difference between groups in SBP and DBP variability

Tolerability

-   -   a. Difference between groups in potentially related side-effects         (dizziness, blurred vision, syncope/collapse/fall, chest         pain/angina, shortness of breath, cough, wheeze, ankle oedema,         skin rash, itching, gout, hyperkalaemia, hypokalaemia,         hyponatraemia, other)     -   b. Difference between groups in mean potassium, uric acid, blood         glucose, cholesterol and fractions, ALT, AST, UACR (Urine         albumin-to-creatinine ratio) and creatinine levels.     -   c. Difference between groups in participant withdrawals from         treatment

Statistical Methods

All analyses of study outcomes will be conducted according to the principle of intention-to-treat. The primary analysis of change in systolic blood pressure (SBP) at 12 weeks will be performed using an analysis of covariance (ANCOVA) including the treatment arm and baseline SBP as a covariate. Continuous secondary outcomes will be analyzed similarly. Additional analyses will include both 6-week and 12-week measurements in a longitudinal model including treatment arm, visit, and treatment by visit interaction as well as the baseline measurement. Within-patient correlations will be modelled using generalized estimating equations. A similar approach will be applied to binary endpoints (e.g. hypertension control) with log-binomial regression used in place of linear regression. There will also be pre-defined subgroup analyses, including by baseline blood pressure, gender, age, and hypertension treatment history. A detailed analysis plan will be developed prior to unblinding.
